TECHNICAL FIELD

[0001] This invention relates to novel pyrrolidinyl and pyrrolinyl ethylamine compounds and their pharmaceutically acceptable salts, and to pharmaceutical compositions containing them. The pharmaceutically active compounds of tics invention can be used as a selective kappa-receptor agonist.

BACKGROUND ART

[0002] Opioid analgesics such as morphine are therapeutically useful, but their usage is strictly limited because of their side effects such as drug dependency and abuse. Thus, analgesics with high usefulness and reduced tendency to cause drug dependency are desired. Considerable pharmacological and biochemical studies have been carried out to discover the opioid peptides and opioid receptors, and the discovery of the subtype of opioid receptor such as mu (μ), delta (δ), kappa (κ) in a variety of species, including human, has made a beginning towards creating new analgesics. As it is thought that opioid analgesics such as morphine act as a mu-receptor agonist, separating the action based on a kappa-receptor agonist from the action based on mu-receptor agonist has been investigated. Recently kappa-selective agonists (kappa-agonists) have been reported from the above viewpoint for example, EMD-61753: A. Barber et al., Br. J Pharmacol., Vol. 113, pp. 1317-1327, 1994. Some of them actually have been studied in clinical trials (Med Res. Rev., Vol. 12, p. 525, 1992).

[0003] European Patent No. EP 0254545 B1 discloses a variety of ethylenediamine compounds. European Patent No. EP 0483580 A2 discloses a vanity of pyrrolidine compounds as analgesics. International Publication WO 96/30339 discloses a wide variety of pyrrolidinyl hydroxamic acid compounds as selective kappa-receptor agonists

[0125] in the absence or presence of a base in a reaction inert solvent.

[0126] General Synthesis

[0127] The kappa agoniists (kappa-receptor agonists) of formula (I) of this invention can be prepared as described in the following schemes. Unless otherwise indicated, in the reaction schemes that follow, A, Ar¹, Ar², R¹, R² and R³ are defined as above.

[0128] In the above Scheme la, an optionally substituted styrene oxide (II) or an optionally substituted phenyl-1,2-ethanediol 2-tosylate (III) can be reacted with a pyrrolidine compound (IV) in the absence or presence of a base such as K₂CO₃ to form a mixture of substituted pyrrolidinyl ethanols (Va) and (Vb) This reaction may be carried out in the absence or presence of a reaction inert solvent (e.g., methanol (MeOH), ethanol (EtOH), isopropylalcohol, tetrahydrofuran (TH), dioxane, N,N-dimethylformamide (DMF), dimethylsulfoxide (DMSO), methylene chloride (CH₂Cl₂), water, benzene, toluene, n-hexane or cyclohexane). This reaction can be carried out at a temperature from −78° C. to the reflux temperature of the solvent, preferably at from room temperature to a reflux temperature of the solvent for 5 minutes to 48 hours, preferably from 0.5 to 12 hours. The compound (Va) or the mixture of the compounds (Va) and (Vb), can be treated with methaaesuulfonyl chloride in the presence of a base such as triethylamine in a proper solvent such as dichloroethane, followed by coupling with a methyl ester compound of formula (VIa) to give an intermediate compound (VII). This coupling reaction can be carried out, in the absence or presence of a base such as sodium hydride (NaM), in a suitable polar solvent such as water, EtOH or DMF, at from room temperature to reflux temperature of the solvent, for 15 minutes to 6 hours

[0129] Then, the intermediate compound (VII) may be treated with a base such as NaOH in a reaction inert solvent such as methanol, at a temperature from 0 to 100° C. for 5 minutes to 12 hours to give a carboxylic acid compound (VIII).

[0130] The carboxylic acid (VIII) can be reacted with an alkyl amine in the presence of a carbodiimide compound to give the pyrrolydinyl ethylaraine compound (I). A convenient carbodiimide compound is 1-ethyl-3-(3-dimeythylaminopropyl)carbodiimide (WSC). This reaction may be carried out by contacting substantially equivalent amounts of the carboxylic acid and alkylamine witl a small exces, amount of the carbodiimide in an appropriate solvent Appropriate solvents are inert aromatic hydrocarbons, ethers, halogenated hydrocarbons, especially dichloromethane The reaction may take place at a temperature in the range from −30 to 100° C., usually from 0 to 30° C. for 30 minutes to 24 hours, usually 12 to 16 hours at room temperature. The resulting product can be isolated and purified by standard techniques.

[0131] If required, the hydroxy protecting group in A of the compound (I) obtained (i.e., Y of —OY), can be removed by the appropriate method for the particular protecting group chosen. For example, a typical protecting group methoxymethyl, can be removed by acid catalyzed hydrolysis in the presence of acid catalyst such as HCl A further convenient protecting group in A is the tetrahydropyanyl group (THP). This can be also removed by acid-catalyzed hydrolysis. Appropriate acid catalysts are organic acids, inorganic acids, or Lewis acids such as acetic acid (AcOH), p-toluenesulfonic acid (p—TsOH), hydrochloric acid (HCl), and dimethylaluminium chloride (Me₂AlCl). Preferred acid catalyst is HCl.

[0132] An optically inactive compound (I) wherein Ar¹ is optionally substituted phenyl, can be prepared by subjecting a corresponding optically inactive 1-phenyl-1, 2-ethanediol 2-tosylate of the formula (III) or 1-phenyl-2-pyrrolidinylethanol (Vb) to the reactions described in Scheme 1a. Optically inactive compounds (III), wherein Ar¹ is optionally substituted phenyl, may be prepared according to the procedures described in for example Tetrahedron, Vol. 47, pp. 9861-9866, 1991, Cehm. Rev., Vol. 80, pp. 187-213, 1980 or J. Org. Chem., Vol. 47, pp. 1229-1232, 1982, followed by tosylation such as reaction with ptoluanesulfonyl chloride in pyridine at 0° C. Optically inactive (Vb) can be prepared according to the procedures described for example in Tetrahedron Lett., Vol. 35, pp. 1511-1514, 1994 followed by a conventional reduction.

[0133] A compound of the formula (I) wherein A is hydroxy, R² is alkoxy and R³ is hydrogen, can be obtained from a methylbenzoate of formula (VII) wherein A is hydroxy. First the hydroxy group of the methylbenzoate compound may be protected with a suitable protecting group such as tert-butyldimethysilyl group. Second the hydroxy-protected methyl ester compound can be subjected to hydrolysis to give the corresponding carboxylic acid. Then the carboxylic acid can be subjected to amidation to give the compound (I). The hydroxy protection can be conducted by subjecting the icompound of the formula (VII) in DMF to a reaction with tert-butyldimethylsilylchloride and immidazole solution at about 0° C. for 1 to 6 hours. The hydrolysis can be carried out in the presence of a base such as sodium hydroxide in a polar solvent such as methanol at about the reflux temperature of the solvent for from 1 to 10 hours. The amidation can be carried out with a desired O-alkythydroxylamine in the presence of a carbod.,imide such as WSC at room temperature for from 1 to 24 hours. If deprotection is required, a conventional procedures can be employed.

The amidation can be carried out in the presence of a base in a reaction inert solvent. The base is preferably triethyiamine and the reaction may be conducted in a suitable solvent, e.g., dichloroethane at about 15° C. If required, the amino protecting group can be removed by the procedures known to those skilled in the art.

[0157] An alternative method to prepare the compounds of the formula (I) is illustrated in the following Scheme 1b.

[0158] The mixture of the compounds (Va) and (Vb) can be treated with methanesulfonyl chloride in a similar way as shown in Scheme 1a, followed by coupling with a cyano compound (VIe) to give the compound of the formula (VIIb). This coupling reaction can be carried out in a reaction inert solvent such as DMF or ethanol, in the presence or absence of base such as NaK NaNH₂ or 2,6-lutidine. This reaction may take place at from room temperature to the reflux temperature of the solvent for 30 minutes to 12 hours.

[0159] Then, the compound (VIIb) may be reacted with a suitable alkoxide such as T-BuOK in the presence of water, in a polar solvent such as t-BuOH.

[0161] The compounds of formula (I) of this invention are basic, and therefore they will form acid-addition salts. All such salts are within the scope of this invention. However, it is necessary to use an acid addition salts which is pharmaceutically-acceptable for administration to a mammal. The acid-addition salts can be prepared by standard methods, e.g., by contacting the basic and acidic compounds in substantially equivalent proportions in water or an organic solvent such as methanol or ethanol, or a mixture thereof The salts can be isolated by evaporation of the solvent. Typical salts which can be formed are the hydrochloride, nitrate, sulfate, bisulfate, phosphate, acetate, lactate, citrate, tartrate, succinate, malate, fumarate, gluconate, saccharate, benzta, t methanesulfonate, p-toluenesulfonate, oxalate and pamoate (1,1′-methyiene-bis-(2-hydroxy-3-naphtoate)) salts.

[0162] The compounds of formula (I) of this invention, wherein Ar¹ is phenyl substituted by carboxy-C₁-C₄ alkoxy are acidic, and they will form base salts. All such salts are within the scope of this invention. However, it is necessary to use a base salt which is pharmaceutically-acceptable for administration to a mammal.

[0163] Also included within the scope of this invention are bioprecursors (also cailed as pro-drugs) of the kappa agonist compounds of the formula (I). A bioprecursor of a kappa agonist of formula (I) is a chemical derivative thereof which is readily conve-,Led back into the parent compound of formula (I) in biological systems. In particular, a bioprecursor of a kappa agonist of formula (I) is converted back to the parent compound of formula (I) after the bioprecuroo has be administered to, and absorbed by, a mammalian subject, e.g., a human subject. For example, it is possible to make a bioprecursor of a kappa agonist of the invention of formula (I) in which one or both of A and R¹ is hydroxy groups by making an ester of the hydroxy group. When only one of A and R¹ is a hydroxy group, only mono-esters are possible. When both A and R¹ are hydroxy, mono- and di-esters (which can be the same or different) can be made. Typical esters are simple allcanoate esters, such as acetate, propionate, butyrate, etc In addition, when A or R¹ is a hydroxy group, bioprecursors can be made by converting the hydroxy group to an acyloxymethyl derivative (e. g., a pivaloyfoxymethyl derivative) by reaction with an acylaxymnethyl halide (e. g., pivaloyloxymethyl chloride).

[0164] The kappa agonists compounds of the present invention of formula (I) exhibit significant agonist activity toward opioid kappa-receptor and are thus useful as an analgesic, anesthetic, anti-inflammatory agent or neuroprotective agent, and also useful in the treatment of arthritis, stroke or functional bowel disease such as abdominal pain, for the treatment of a mammalian subject, especially a human subject.

[0165] The activity of the kappa-agonists compounds of formula (I) of the present invention, is demonstrated by the opioid receptor binding activity. Such activity mav be determined in homogenate from guinea pig whole brain, as described by Regina, A. et al.,. in J. Receptor Res., Vol. 12: pp. 171-180, 1992. In summary, tissue homogenate is incubated at 25° C. for 30 min in the presence of labelled ligand and test compounds The mu-sites are labelled by 1 nM of (3H)-[D-Ala2,MePhe4,Gly-ol5]enkephalin (DAMGO), the delta-sites by 1 nM of (3H)-(D-Pen2,5]enkephalin (DPDPE) and the kappa-sites by 0.5 nM (3H)-CI-977. The non specific binding is measured by use of 1 μM CI-977 (kappa), 1 μM (DAMGO) (mu), 1 μM (DPDPE) (delta). Data are expressed as the IC₅₀ values obtained by a non-linear fitting program using the Cheng and Prusoff equation Some compounds prepared in the Examples showed a potent ICso value against kappa receptor in the range of 0.01 to 100 nM.

[0166] The analgesic activity of the kappa-agonist compounds at the central nervous system can also be demonstrated by the Formalin Test as described by Wheeler-Aceto, H. et al. in Psychopharmacology, Vol. 104: pp. 35-44, 1991. In this testing, male SD rats (80-100 g) are injected s.c. with a test compound dissolved in 0.1% methyl cellulose saline or vehicle. After 30 min., 50 μl of a 2% formalin are injected into a hind paw. The number of licking the injected paw per observation period is measured 15-30 min. after the injecio of fbmaain and expressed as % inhibition compared to the respective vehicle group. Some compounds prepared in the Examples showed a potent ED₅₀ value in the range of less than 25 mg/kg p.o.

[0167] The activity of the kappa agonists, against peripheral acute-pain, can be demonstrated by the Randall-Selitto assay (M. E. Planas, Pain, Vol.60, pp. 67-71, 1995). lathis testing, MaleSD rats (100-120 g) were used and the nocceptive threshold at the right paw was measured by Randall-Selitto (Ugo Basile) method. After three days of acclimation of assay condition, experiments were carried out. Hyperalgesia was induced by the intraplantar injection of a 0.1 ml/right paw of 1% solution of carrageenin. Painful pressure were delivered to the right plantar via a wedge-shaped piston and the level of response were measured at 3.5 and 4.5 hr later the carrageenin injection. Some compounds, prepared in the working examples as described below, were tested in accordance with the above procedures, and showed good activity against acute-pain (i.e., ED₅₀ value of less than 10 mg/kg p.o.).

[0168] The activity of the kappa agonists, against chronic pain at the periphery, can be demonstrated by the adjuvant-induced hyperalgesia, according to the procedure described by Judith S. Waker el al., as reported in Life Sciences, Vol. 57, PP. 371-375, 1995. In this testing, male SL rats, weighing 180-230 g at the time of inoculation, were used. To produce adjumant arthritis, rats were anesthetized with ether and inoculated intradermahly into the footpad of the right hindpaw with 0.05 ml of Mycobacteriun butyricum suspended in paraffin oil (2 mg/ml). Nociceptive threshold was evaluated by paw pressure test, using same procedures of the Randall-Selitto assay (as being described above), and edema was measured as the width of foot. Assays were done through the whole period.

[0169] The sedation function of kappa agonists can be determined by the Rotarod Tes; as described by Hayes, A. G. et al. in Br. J. Pharmacol., Vol. 79, pp. 731-736, 1983. In this testing, a group of 6-10 male SD rats (100-120 g) are selected for their ability to balance on a rotating rod (diameter 9 cm, rate of rotation 5 r.p.m.). The selected rats are then injected s.c. with a test compound dissolved in 0.1% methyl cellulose saline The animals are tested again 30 min. after treatment; a rat falling off the bar more tha twice within 150 seconds is considered to be showing motor impairment and the animal's perform ance (i. time on the-rotarod) are recorded. The ED₅₀ value, defined as the dose of the drug which have the performance time is observed in the control group Some compounds prepared in the working examples as described below, were tested n accordance with the above procedures.

[0170] The diuresis function of the kappa agonists can be determined according to the procedure described by A. Barber et ai., (Br. J. Pharmacol., Vol. III, pp. 843-851, 1994). Some compounds, prepared in the working examples as descnbed below, were tested in accordance with the above procedures.

A preferable dosage level may be in a range of from 0 01 mg to 10 mg per kg of body weight per dab, although variations will necessarily occur depending upon the weight and condition of the subject being treated, the disease state being treated and the particular route of administration chosen. However, a dosage level that is in the range of from 0.01 mg to 1 mg per kg of body weight per day, single or divided dosage is most desirably employed in humans for the treatment of pain in a postoperative patient and a pain tlke hyperalgesia caused by chronic diseases.

[0172] The compounds of the present invention may be administered alone or in combination with pharmaceutically acceptable carriers or diluents by either of the above routes previously indicated, and such administration can be carried out in single or multiple doses. More particularly, the novel therapeutic agents of the invention can be administered in a wide variety of different dosage forms, i.e., they may be combined with various pharmaceutically acceptable inert carriers in the form of tablets, capsules, lozenges, trochees, hard candies, powders, sprays, creams, salves, suppositories, jellies, gels, pastes, lotions, ointments, aqueous suspensions, injectable solutions, elixirs, syrups, and the like. Such carriers include solid diluents or fillers, sterile aqueous media and various nontoxic organic solvents, etc. Moreover, oral pharmaceutical compositions can be suitably sweetened and/or flavored. In general, the therapeutically-effective compounds of this invention are present in such dosage forms at concentration levels ranging 5% to 70% by weight, preferably 10% to 50% by weight.

[0173] For oral administration, tablets containing various excipients such as microcrystalline cellulose, sodium citrate, calcium carbonate, dipotassium phosphate and glycine may be employed along with various disintegrants such as starch and preferably corn, potato or tapioca starch, alginic acid and certain complex silicates; together with granulation binders like polyvinyipyrrolidone, sucrose, gelatin and acacia. Additionally, lubricating ag such mar stmme, so lsuixiyl sulte and talc are often very useful for tabletting purposes. Solid compositions of a similar type may also be employed as fillers in gelatine capsules; preferred materials in this connection also include lactose or milk sugar as well as high molecular weight polyethylene grycols. When aqueous suspensions and/or elixirs are desired for oral administration, the active ingredient may be combined wit varous sweetening or flavoring agents, coloring matter or dyes, and, if so desired, emulsifying and/or suspending agents as well, together with such diluents as water, ethanol, propylene glycol, glycerin and various like combinations thereof.

[0174] For parenteral adrninistration, solutions of a compound of the present invention in either sesame or peanut oil or in aqueous propylene glycol may be employed. The aqueous solutions should be suitably buffered (preferably pH>8) if necessary and the liquid diluent first rendered isotonic. These aqueous solutions are suitable for intravenous injection purposes. The oily solutions are suitable for intra-articular, intra-muscular and subcutaneous injection purposes. The preparation of all these solutions under sterile conditions is readily accomplished by standard pharmaceutical techniques well-known to those skilled in the art. Additionally, it is also possible to administer the compounds of the present invention topically when treating inflammatory conditions of the skin and this may preferably be done by way of creams, jeffies, gels, pastes, ointments and the like, in accordance with standard pharmaceutical practice.
